You're wrong. You have to change the two measurements into the same units before working out x.
For example, in the first one, you have 7 inches and 14 feet. But 14 feet is 14x12 = 294 inches. So you should calculate x based on 7 inches and 294 inches.

1. No, the factor is 2, but it's not inches to inches. You also have an inches/feet factor.
2. correct - cm to cm
3. Wrong - same thing as #1. figure out how many feet is 10 inches (a fraction).
4. Same thing.

1. x= 2, the correct answer would be 24
2. x=6 is the right answer
3.x=1.2 is wrong, like problem 1, you need to multiply this number by 12 to get 14.4
4. x=1.5 is wrong since 12 in is 1 foot, and the real height is 8 feet, x=8.
